JENNIE SPURRIER, OF SPRINGFIELD, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 313,116 dated March 3, 1885.

Application filed March 29, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, JENNIE SPURRIER, a citizen of the United States, and a resident of the city of Springfield, in Sangamon county, in the State of Illin0is,have invented new and useful Improvements in Adjustable Fasteners for Mosquito-Bars, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

Figurel isa perspective view of a post of a bedstead with my invention applied. Fig. 2 is a side elevation of the clamp. Fig. 3 is a side elevation of the clamp, showing fastener or clamping-bar.

Similar letters refer to similar parts throughout the several views.

The bows or rods A, which support the mosquito-netting, areinserted in the groove F, and are fastened by the clamps G O,which are held in position by the set-screw G. The clamping-bars D D, which move on the pivot-screw E, hold the mosquito-netting firmly in position at the four corners of the bedstead.

My invention may be applied to any bedstead, crib, chair, or other device for reclining or sleeping, and may be made of wood, brass, or any other suitable material.

The clamps C O are made like an ordinary clamp, having a set-screw, G, on one of its sides, provided at the ends with a flat disk to prevent marking or indenting the wood-work, and are provided with grooves F on the inner side, in which the ends of the rods or bows A, which support the netting, are inserted. To these clamps are attached, by means of the pivot-screws E E, the clamping-barsD D. These clamping-bars are beveled or convexed on the side next the clamp, and are fitted into a concaved shoulder on the metallic clamp, so that when closed they hold the netting firmly in position.

. The operation of my invention is as follows: The netting B being spread upon the bows or supportingrods A A, is properly adjusted. The surplusage of the drapery is gathered at the corners of the bedstead into folds and placed upon the concave surface of the metallic clamp. The clamping bar D is then closed upon the folds of netting.

, It is obvious that to withdraw the netting from this device by force in any direction except that which opens it would tighten the clamping-bar.

The clamps are made rights and lofts.

Having described my invention, what I desire to claim, and secure by Letters Patent of the United States, is-

1. As an article of manufacture, a clamping device consisting of a frame having three sides, one of the opposite sides being provided with an adjustable screw, and the other with a movable bar or jaw, D, said jaw being pivotally attached thereto and closing upon said frame, as shown in drawings, so that the strain on the material keeps it closed, substantially as set forth.

'2. As an article of manufacture, a clamping device consisting of a frame having three sides, one of the opposite being provided with an adjustable screw, and the other with a groove opening on the inner side of said frame, and a movable bar or jaw, D, said bar or jaw being pivotally attached thereto and closing upon said frame, as shown in drawings, so

that the strain on the material keeps it closed.
